Phormium plant named ‘Chocomint’

ABSTRACT

A new cultivar of hybrid  Phormium  named ‘Chocomint’ that is characterized by its foliage that is variegated with purple-brown centers and wide bright green margins, its stiff leaves, and its slightly arching plant habit.

Botanical classification: Phormium cookianum×Phormium tenax.

Cultivar designation: ‘Chocomint’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from similar parentage in the Inventors' breeding program that is entitled Phormium Plant Named ‘Moonraker’ (U.S. Plant patent application Ser. No. 12/661,442).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phormium named ‘Chocomint’, an interspecific hybrid of Phormium cookianum×Phormium tenax and referred to hereafter by its cultivar name, ‘Chocomint’. The new cultivar is grown for use as a foliage plant for landscape and container use.

The Inventors discovered the new cultivar summer of 2000 as a naturally occurring chimeral mutation of Phormium ‘Yellow Wave’ (not patented) in a container block in their nursery in Tauranga, New Zealand.

Asexual reproduction of the new cultivar was first accomplished by division in autumn of 2000 in Tauranga, New Zealand by one of the Inventors. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Chocomint’ as a new and unique cultivar of Phormium.

-   -   1. ‘Chocomint’ exhibits foliage that is variegated with         purple-brown centers and wide bright green margins.     -   2. ‘Chocomint’ exhibits stiff leaves with a slightly arching         plant habit.

‘Chocomint’ can be compared to the parent plant, ‘Yellow Wave’. ‘Yellow Wave’ differs from ‘Chocomint’ in having foliage with variegation that is yellow, green, and cream in color and in having leaves that are less stiff. The closest comparison cultivars are ‘Co-ordination’ and ‘Sea Jade’ (both unpatented) as they are similar in having leaves with green and brown variegation. ‘Co-ordination’ differs from ‘Chocomint’ in having narrower leaves, a more upright habit, and in having leaves with lighter bronzy brown centers rather than the darker purple-brown of ‘Chocomint’. ‘Sea Jade’ differs from ‘Chocomint’ in having leaves that are wider with lighter green margins and bronzy brown centers, and in having a strongly upright and taller plant habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Phormium.

The photographs in FIG. 1 and FIG. 2 were taken of a two year-old plant of ‘Chocomint’ as grown outdoors in a 3-liter container in Auckland, New Zealand.

FIG. 1 provides a side view of ‘Chocomint’ and

FIG. 2 provides a close up view of the foliage of ‘Chocomint’. The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Phormium.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of two year-old plants of the new cultivar as grown outdoors in 3-liter containers in Auckland, New Zealand. The plants were grown under average day temperatures of 20 to 27° C. and average night temperatures of 12 to 20° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
